Overview

The Singapore dollar is the official unit of currency of the Republic of Singapore. Its ISO code is SGD and it is commonly written with the prefix S$ to distinguish it from other dollar-denominated currencies; the plain dollar sign $ is also used in local contexts. The basic subdivision is the cent, with 100 cents equal to one Singapore dollar.

Denominations and design

Banknotes and coins in issue have varied through successive series, and designs often incorporate national symbols, local industries and celebrated figures. Commonly seen denominations include the following:

  • Coins: 5¢, 10¢, 20¢, 50¢, $1 and $2 are generally in circulation; smaller denominations have fallen out of routine use.
  • Banknotes: notes are issued in several denominations to serve everyday payments and larger transactions; historically and in some series, high-value notes have existed for wholesale or reserve use.

Issuance and monetary authority

The Monetary Authority of Singapore (MAS) is the central bank and currency issuer responsible for the design, issuance and integrity of banknotes and coins. MAS also supervises currency circulation, anti-counterfeiting measures and the overall stability of the monetary system.

Monetary policy and use

Singapore's approach to monetary policy is notable for emphasizing exchange rate management as the principal nominal anchor: MAS operates a managed float of the currency within an undisclosed policy band and adjusts that policy to meet inflation and growth objectives. The Singapore dollar is the medium of exchange for domestic commerce and financial transactions and is widely accepted in the city-state's banking and retail sectors.

History and notable facts

The modern Singapore dollar replaced the Malayan dollar and other earlier currencies as the city-state established its own monetary system. Over time, a number of note series and coin types have been issued reflecting economic development and national identity. A distinctive regional feature is the bilateral Currency Interchangeability Agreement under which Brunei dollars and Singapore dollars are accepted at par in each other's territory, a practice that remains a notable example of currency cooperation.
